To be honest, I tend to forget about the whole ronin thing between chapters and I constantly have to remind myself that it's the reason why it's called slow start . It's been of so little importance to the plot that Hana shouldn't even bother talking about it at this point.
That and Hana has sorta major insecurity issues in general. They're not that conspicuous these days (emotionally fulfilling social life tends to help) but this particular matter is her personal bête noire.
Huh, Shion's are not popping out of frame on any page, although there's multiple opportunities. Is the author all right? Also, I'd worry a bit about a person who can't tell dreams from reality after they've woken up.
